Judging by your escalating use of caps and exclamation marks, I would say that finals are almost getting the better of you. Don't worry -- all done tomorrow!

Observational skills of the highest order ...
tried to rep, but fell foul of the blue meanies ...
It depends very much on relative molecular mass ...
For most molecules you encounter VDW are definitely weaker. What's the typical difference.... ~ 4 orders of magnitude for most systems. Yes of course for colloids or other systems this goes out the window.

It's much less dramatic than that.
Why are iodine or sulphur solids at room temperature?
HI and H2S are polar and both gases ...
You can say that "given similar molecular masses" dipole-dipole forces are important, but you can't say that they are "per se" stronger than induced dipole-dipole interactions.

My main problem is determining which molecules are more polar than another, I know fluorine is the most electronegative element but don't have a clue when they talk about NH3 being polar?
